Weave Router
Prompt-level model router with an OpenAI-compatible endpoint
Featured by Willet
What it is
A Go service that sits between agentic tools and model providers, picking a suitable model for each prompt so cheaper models handle simpler requests. It exposes an OpenAI-compatible endpoint, so tools such as Claude Code or Codex can point at it by changing only the base URL. Teams running coding agents at scale deploy it to lower their model spend without rewriting their integrations.
